A frame in social theory is a schema of interpretation that individuals rely upon to understand and respond to events. Collective action frames are persuasive communications constructed during mobilization campaigns, frequently to call attention to a perceived problem or issue, itemize steps to resolve the issue, and motivate others regarding the issue's urgency and the importance of taking action [e.g. 1]. There is substantial empirical evidence that framing rhetoric influences the success or failure of social movements, and that movement members are increasingly relying upon social media to communicate their frames. Consequently, there is considerable interest within the security informatics community to develop methods for detecting framing rhetoric in social (and other) media [2]. Particularly valuable would be computational methods capable of distinguishing framing from non-framing content using only limited labeled examples of framing discourse, because generating such labels typically requires experienced analysts and is an expensive and time-consuming undertaking.
